Title: Semiconductor device
Inventor: TERASAKI TAKESHI
IPC: H01L21/60
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To accomplish a highly reliable semiconductor device on which the fatigue life of a solder bump can be extended. SOLUTION: The diameter of the area equal to the area of the part, which comes in contact with the pad 9 or the pad 10 of a lead-free solder bump 7, is set as A size and the diameter of the sphere of the cubic volume equal to the cubic volume of the lead-free solder bump 7 is set as B size. In this case, when the A size of the solder bump 7 is formed in the size which is 0.8 to 1.1 times of the B size, the contact surface of the solder bump 7 and the pads 9 and 10 is increased, and the intensity of junction interface is increased. Also, in proportion to the A-size becoming larger, it becomes cylindrical shape, the regidity of the solder bump 7 itself becomes higher, and the amount of thermal deformation added to the solder bump 7 becomes small.

Title: Carrier recovery circuit
Inventor: MATSUE HIDEAKI
IPC: H04L27/00
Filed: 1985-06-07
Abstract: PURPOSE:To realize easily a mode switching control method where only a selection control is adopted at synchronization locking and the non-selection control only is adopted at the synchronization stability by applying external a discrimination signal for synchronizing/asynchronizing state. CONSTITUTION:A signal superimposing the output of a low frequency sweep signal source 52 on a VCO control signal outputted from an LPF 46 by an adder circuit is used as a monitor signal for synchronization/asynchronization. The amplitude of the sweep signal of the control voltage of a VCO is small at the synchronization locking state and does not almost appear. On the other hand, the sweep signal appears as it is at the synchronization. Thus, a signal monitoring synchronization and asynchronization is obtained at an output terminal 57 by rectifying the signal by a whole wave rectifier 54, smoothing the signal by a filter 55 and discriminating the signal by a gate circuit 56. The carrier recovery circuit switching the control mode in response to the synchronizing state is realized by connecting the terminal 57 to an input terminal 50.

Title: Reel controller
Inventor: HATA TETSUO
IPC: G11B15/46
Filed: 1987-05-20
Abstract: PURPOSE:To run a tape at a fixed high speed immediately after tape insertion by providing a counter, which counts the number of FG pulses due to reel rotation at the time of tape loading for the purpose of obtaining a proper number of rotations at the time of starting a reel motor, and a calculating part which calculates it. CONSTITUTION:When a tape winding signal is received, a switch B16 is switched to the side of a contact (a) and enough voltage to obtain a tape speed Vt is applied to the reel motor to start winding. A clock (f) from a clock generating part 4 is used to count the cycle of the FG pulse of a reel A2 by a counter A16. A comparing part A11 compares this counted value Ca with an output Cr of a latch part A9; and if they coincide with each other, it is judged that the tape speed reaches the desired value Vt and a coincidence signal Se is outputted to a latch part B10 and the switch B16. A calculating part 8 outputs a output value S1 of a latch part B. Thus, the tape is wound at a desired fixed speed immediately after tape insertion.

IPC: G06F3/153
Filed: 1985-06-06
Abstract: PURPOSE:To improve the reproducibility of a character by executing a hard copying by performing an interpolation by a dot corresponding to the respective conditions that a picture element exists, and does not exist, when interpolating a video signal on which a display signal is not loaded. CONSTITUTION:A sampling circuit 10 samples a data of a raster number 1, and stored it in the second memory 40 through the first memory 20. Subsequently, a data of a raster number 2 is sampled, and written in the first memory 20. A CPU 60 checks a logic of the data of the raster number 2 in order of a dot. In case the logic is '0' (no picture element exists), the data being in a position of b1 is interpolated to, for instance, a position of a1, on the second memory 40. On the other hand, in case of the logic is '1' (a picture element exists), the data being in a position of, for instance, a2 is written as it is in the second memory 40. In such a way, a character shown in Y1 is brought to a hard copy as shown by Y2 or Y3.

Title: Semiconductor memory
Inventor: NANBU HIROAKI
IPC: G11C11/414
Filed: 1990-05-16
Abstract: PURPOSE:To accelerate time for inverting a cell and for writing by setting a potential VB of a bit line to impressing voltages VC and VE of the memory cell to be VB<VE when writing a data to the memory cell, and reducing the differential voltage of VC-VE. CONSTITUTION:In order to accelerate access time when reading out information while switching a select word line, the amplitude of the voltage signal of the word line is lowered from 2.4V to 1.6V. Namely, a non-select level VWL of the word line is increased from -3.2V to -2.4V. Therefore, in the case of the VWL (-2.4V), it is necessary to increase the potential VE as well to the VWL (-2.4V) so that transistors MTL and MTR can not be turned on. Since a normal memory sets the potential VE and a potential VBL of the bit line in the case of writing to be VR<=VBL, the write time is delayed when increasing the VBL only for the increased component of the VE. In this case, the VBL is set to -3.0V and made lower than the VE (=2.4V) and the On resistance of the MPL or MPR in the case of writing is reduced. Then, the time is accelerated for inverting the memory cell and writing the data.
